Subject: [PATCH AUTOSEL 4.4 2/4] usb: gadget: composite: Clear "suspended" on reset/disconnect
Date: Tue, 20 Aug 2019 09:43:23 -0400	[thread overview]
Message-ID: <20190820134325.11825-2-sashal@kernel.org> (raw)
In-Reply-To: <20190820134325.11825-1-sashal@kernel.org>

From: Benjamin Herrenschmidt <benh@kernel.crashing.org>

[ Upstream commit 602fda17c7356bb7ae98467d93549057481d11dd ]

In some cases, one can get out of suspend with a reset or
a disconnect followed by a reconnect. Previously we would
leave a stale suspended flag set.
